The Siege of Terra is the concluding chapter of the Horus Heresy, Black Library’s multi-author epic chronicling the civil war that nearly destroyed the Imperium of Man ten thousand years before the events of Warhammer 40,000. The series covers the final battle of that war: Horus Lupercal’s assault on Terra with his combined Chaos forces against the Emperor of Mankind and the loyalist Space Marine Legions defending the Throneworld. Dan Abnett, who wrote the first Horus Heresy novel in 2006, opened The Siege of Terra with Sons of the Selenar and The Solar War.
The series was planned to conclude the narrative that Black Library began in 2006, and it features the same multi-author format with contributors including John French, Guy Haley, Nick Kyme, and Graham McNeill alongside Abnett. The 16-volume arc covers the Solar System blockade, the breaching of the Palace walls, the battle inside the Imperial Palace itself, and the confrontation between the Emperor and Horus that ends the Heresy. The three-part End and the Death sequence closes out the war, with Abnett writing the final volume.
The series should be read in the numbered order provided, as the events build directly on each other across all 16 books. The Siege of Terra represents one of the largest coordinated storytelling projects in tie-in fiction, and its conclusion has been anticipated by Warhammer fans since the Horus Heresy series began.
